Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Replaying GSS-TSIG signed UDP messages can result in memory corruption in "`named`". An attacker who can

 code execution. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0
 through 9.21.26, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1. (CVE-2026-94300)
